Hi Otto!

In these times it is virtually impossible to visit internet pages (including this forum) without javascript enabled.

This forum (and the old version 1.x) works wonderfully without JavaScript (and even without CSS - which is nice for screenreaders). OK, in v2 of course there's no Ajax-preview, BBCode, link and image-insertion, etc, but the basic functionality is still available.
Especially 'in these times' in big companies JavaScript is deactivated by net-admins on client machines according to firm's safety policy (according to my logs about 5-10% of visitors are using the forum without JavaScript). If you rely on JavaScript you are forcing Users to wait until they are at there home-PC to answer.

So, why still bother for those dinosaur users who still don't use javascript?

It's up to you; I just pointed out some reasons why it may not be desirable...
