All - As of this past Tuesday, I changed the forums on this site to require a number of posts before you can have a signature. I resisted this change for a long time, but with the absolutely pathetic spammers we have on here, I had to do it.
There seems to be a higher number of spam originating from Indian
SEO firms lately and I guess one of their tactics is to use signature files along with the straight forward spam.
So, if you are a regular here, you will notice no difference. If you are new, create some good posts and you too can have a signature.
