Its a recursive error. Gotta report these bugs, but they will say, if it ain't broke, don't fix it. If you notice, you are already in my friend list. means, just like when you post a VM, it gives you the same error, something like, the following errors occurred with so and so, when actually the request has been processed successfully. Definitely a site error, but the fact of the matter is that you are in my friend list, however buggy the forum might be.
