I have touchdown it didn't work well with my works server?
How do I make a note to copy and paste?
I think touchdown will do it. It's a bit pricey - $20 in the market. I just keep my sig in a note and copy it and paste it into an e-mail before I send it.
Just download a note app (evernote, quicknotes, whatever) and make a note of your signature. You can then copy that text and leave it in your clipboard to paste.
