Access your signature through the top link My Blab > Edit Signature.
All members may design their own signature area that appears below each post.
You can make adjustments in your My Panel area (see link in the upper right of the forum header.)
If you have specified a signature, then the forum will automatically append your signature to any messages you post.
You can disable signatures on a per-post basis by un-ticking the 'Show Signature' checkbox when you compose your message.
You may turn the signature on and off on posts you have already made by editing the post and altering the
state of the 'Show Signature' option.
Signatures may be no more than 200 pixels tall and 600 pixels wide, including all images and text.
To edit your signatures, see the instructions for
adding images, links, and text effects to posts. Signatures work the same way.
To ensure your signature is within size parameters by visually comparing it with an example, follow
this link to a signature help thread.
