Funny to read that so many new members in EB only complain that they have problems sending pm. No intro, not reading about the rules here before registering hence not sharing informations with other users.
The admin/mods should not change anything at all with the system they had implemented in fact they should even make the rules more tight (my point of view).
How about one can send one pm after proper introduction has been made, another pm can be send after the person open a new thread.....the more new members following the guideline and being active here the more option they will get to use the pm options.
