I think it is stupid. You already have the nickname/handle, we know who posted it. It is not possible to fake for other poster your post and if it was, he could sign your name anyway. So, don't sign your post, it is redundant...
Bit pointless signing and a bit pointless mentioning it, Like said it's not like someones going to ID theft your post. Light and Love, Spuriousmonkey
I dunno, especially seeing as you have to keep typing it. Maybe you get used to doing it all the time, and start doing it automatically. Sincerely yours, Forever and ever, Amen.
