Suggestion Box

Hi Chy,

Signatures are automatically applied to forums, books and email. If you have a premium membership, you can tell your account to manage/apply specific signatures to specific forums, including a blank signature for your blog if you wish.

As an alternative, with an upgraded account, you could skip using the signature block and use macros. Then click in whichever signatures you'd like to use in each forum. More about macros here: "Macros" 

Hope that helps,
Leger~
