Thanks, I've done that and when hitting Submit on registration:

Using $this when not in object context on line 4 in /{ROOT}/dbtech/usertag/hooks/postdata_presave.php
#0 /{ROOT}/register.php(492) : eval()'d code(14): require()
#1 /{ROOT}/register.php(492): eval()
#2 {main}


Fatal User Error: Using $this when not in object context on line 4 in ..../dbtech/usertag/hooks/postdata_presave.php in ..../vb/vb.php on line 286

Edit:
A little more information:
The registration is successful (you can verify via e-mail and login) but no welcome thread is created.
