The Results

This week's quiz regarding the placement of the rubber's identification information had one choice that was the most popular by quite a ways (Option 2 - near the handle, but with a small gap allowed), with the other options sharing the votes fairly equally, except for option 4 (no rubber identification information needed at all), which lagged well behind.
Results at the time of writing are as follows:


Option 1: 11 votes (17%)
Option 2: 30 votes (46%)
Option 3: 9 votes (14%)
Option 4: 5 votes (7%)
Option 5: 9 votes (14%)

with a grand total of 64 votes.

The Answer

As some of you might have realized by now, this question had a little twist in it, the twist being the recent changes to the ITTF Handbook for Match Officials, which had a new edition published in December 2010.
Up until the new edition, the correct answer to the quiz question would have been Option 3 - Near any edge of the racket is fine, provided all the necessary information is visible. This is because in the old edition, the relevant rule was:

7.1.2 In competitions played under international regulations the covering must be of a type authorised by the ITTF. Coverings authorised in this way carry the ITTF logo and the maker’s logo or trademark, and players are required to attach the rubber to the blade so that these identifying features are clearly visible near the edge of the striking surface so that they can be checked by the umpire.

Note that no mention of which edge was made by the rule, so in theory it was perfectly legal to put the rubber on the blade so that the identification information showed up on either side edge, or even the top edge if your racket had a flat enough top edge to show all the necessary information. Of course, in reality, virtually no-one actually did this, since very few people want the lumps and bumps of the indentification information running along the top or side edge of their racket! The fact that it has to be near an edge also made Option 5 (put it anywhere at all) incorrect.

Also note that to play in competitions played under international regulations (which is generally any competition which adopts the ITTF rules), the player's rubbers must be attached with the rubber identification information visible, which means Option 4 (Nowhere, provided the rubber meets all other ITTF regulations for maximum thickness, pimple density, glossiness etc.) is not correct.

All this changed with the coming of the new edition of the Handbook for Match Officials, since the rule has now been changed to:

7.1.2 In competitions played under international regulations the covering must be of a type authorised by the ITTF. Coverings authorised in this way carry the ITTF logo and the maker’s logo or trademark, and players are required to attach the rubber to the blade so that these identifying features are clearly visible near the handle of the striking surface so that they can be checked by the umpire.

Note the change of the wording from "near the edge" to "near the handle", which means that now the rubber indentification information must be placed near the handle of the blade.

How Near is Near?

With that out of the way, the only thing left to determine is whether you have to put the rubber right next to the handle, or whether you can leave a small gap between the rubber and the handle. This question is decided by ITTF Law 2.04.04, which states:
2.04.04 The covering material shall extend up to but not beyond the limits of the blade, except that the part nearest the handle and gripped by the fingers may be left uncovered or covered with any material.

So a gap is allowed between the rubber and handle in order to allow the player's fingers to get a better grip, if so desired.

Conclusion

So previous to December 2010, the best answer to the quiz question would have been Option 3 - Near any edge of the racket is fine, provided all the necessary information is visible, since any edge of the racket could be chosen to display the rubber identification information.
Post December 2010, due to the small but important change it the ITTF's wording of the rules, the correct answer is now Option 2 - Near the handle, but a small gap between the rubber and the handle where the fingers grip the racket is allowed.
