> I'm going to try starting at 3000 now to resolve the Invalid or Virtual Namespace -1 errors when I try to create forms with Semantic and Semantic-Forms.

I'm not sure what issue you have with SMW's default namespace but SMW NS range has been used fairly early before the whole NS number n....... came up therefore if you leave the NS as deployed you should not face any issue.

In case you want to use a different NS then you advise to read:
