SBC Yahoo! GeoCities site. What you get free is 15MB of space with ADS, no FTP access.
If you are a legacy ameritech.net customer who never migrated to Yahoo!, you can access your 2 MB of personal web space at the Ameritech.net Member Site.
(01-05-2004) Rumor has it that the "legacy" webspace is going away soon. Better retrieve anything you have stored there for safekeeping.
(09-26-2004) Seems that you can actually link to items stored in your Geocities "free" webspace these days. Someone will be fired for offering a useful feature, so enjoy!
If you did migrate to SBCYahoo, use your firstname.lastname@example.org login and password to access your Geocities webspace. It may be prudent to create a subaccount for webspace use since the URL contains the whole email address...
