Text signature shows extra characters
When creating a new message to send, text signature shows extra characters "--" before the actual signature.
This seem to hold true if the signature is created in TB or is the identical text read from a text file.

The -- is the signature separator, a standard element to prevent recipients from quoting the signature when they reply to your message.

Thanks. First I've heard of that. I guess I need to consider the ramifications of turning that off.
As a tangent, maybe needing a new thread, I find attempting to use a file for "rich text" or other formats causes the signature to seem "garbled" displaying what seem to be file and formatting information.
Is that a different issue?
That's a different issue. If you make an html signature file with anything besides the TB message composer, you're more likely to encounter formatting problems.
