Member nickname

Im running Dolphin 6.1.2 and I love it. I am however having an isssue with the nickname on signup. I am trying the follwoing member name but it will not allow them to create it : BedSydeStranglrs

It is saying that you can only use latin symbols or underscores or minus.

This nickname looks fine to me.

How can I change this to pretty much accept anything?

Thanks,

Tom

Curious on this one... Could it be because you have caps & lower case throughout the entire SN?  I've never used 6.1.2 so I don't have an answer to this question, heck I don't even have a copy to test for you.
