Hi,
I noticed the same. I tried to edit my post, although I entered and SAVED the changes the post was not changed. Before the forum update someone was able to edit his post for a limited time (and no immediate followed reply from an other user?!), which makes sense to me instead creating a new post and to avoid additional reading and associated confusion.
I'm anoyed that I'm not able to edit my post, and not about the lost points.
Further, I used Italic style for two words, afterwards most of the text was italic.
greets
