Hi zephy
There was a bug in jOpenSimRegister 0.3.1.5 when set to optional but "allow same name" was set to "no".
It was fixed in 0.3.1.5.2 but just see I forgot to replace the download files
You can get it quickly from
www.jopensim.com/jopensim3/plg_user_jope...gister.0.3.1.5.2.zip
and let me know pls if this solved it.
