It's a pity we can edit the post only a few minutes after submitting it. From my point of view, one of the biggest disadvantages of Yahoo Group was that I was unable to edit/correct my posts after submitting. Let me explain why:
1) English is not my native language. I do my best to compose a post properly and avoid any mistakes before submitting, but especially when it is a long one (with lots of text, links, pictures etc) I can't be sure that it is 100% correct. Not that seldom I find things that I would like to correct after some time - when I read my post for the n-th time - even after couple of days.
2) When the post contains external links, they usually become outdated after some time. Being able to edit it, means we can update them easily.
3) Some posts need to be updated. Let me provide an example. In this post (on the other forum) Link I write about some ways of making execution of AFL code even faster (some performance tuning tips). At the end of the post I list all changes in consecutive versions of AmiBroker which have something to do with performance. I made this post over a year ago, but thanks to the fact that I can still edit it (and I did it today) it still contains up-to-date information.
@Tomasz maybe you consider some arguments for enabling editing our posts ...
