Signature question

Hi guys,

If I haven't used a signature yet is it possible to create one now that appear also on my old posts?

 

Doesn't the signature automatically go on all your posts?

 

Nah not all of them.

I'm not sure how many though.

 

I think it is not possible. Try to add signature and see the effect . If this is possible you can see it ..

 

FAQ Says `

So I believe your signature will be displayed on each and every post you made starting on day 7/8 after you joined, but not in those before that day regardless you posted over 10.

 

It will appear on all questions and post.

 

Some websites have retroactive signature allowance.
Not sure if this one does.
Will have to try indeed.
