Tripod isn't great for remote linking, nor is Geocities. You can try one of the following:
http://mywebpage.netscape.com (if you have an AIM name, you're already registered)
http://freehomepages.com (I believe they give you 50MB and lots of bandwidth)
Alternately, there's a hack to
upload signatures, but I think it's best to upload them to your own site instead of using space on AHS.
