Tools for generating email signatures
Google is getting generous and tons of GMail invites are now available. You don't need to be a Photoshop expert to generate that cool looking GMail signature graphic. Just check out these two Gmail Signature Generator sites:
Gizmo
Playtime
Playtime allows you to download the source code of the gmail signature generator script but I personally like the styles of gizmo967.
Both these services are very simple to use: Enter you GMail username, click the 'Create' button and save the generated graphic as a .png file. Convert it other formats like .jpg or .gif using free tool like IrfanView. Done ! And putting a graphic instead of the email prevents you from spam as well.
