Sorry for the serial posts, but there is a huge problem with this hack. If a user puts in a bogus entry, any thread with that user will get a big error message passed from magpie. There needs to be a way to suppress errors.
It would also be a good idea when creating the custom profile field to get a good REGEXP to validate URLs. I'm looking for some code that will work. If you have it, please post to this thread:
