It says iv sent too many messages today, Im from the Uk its now the next day and its still saying its blocked ? Does anyone know when this resets ?

I'm not sure. I know that once someone replies to you that you can chat with them without limits.

Woah stud, what if they all reply Welcome man

You may indeed have been caught up on time zones :-)

Why did I encounter an email limit?
'We had to place a limit on first-contact emails because
of spammers. Basically, this cuts down the number of
first-contact emails that one can send within a
two-to-three-day period (we can't divulge anymore
information about this limit). However, a member
affected by this limit will still be able to send an
unlimited number of emails to those with whom he or
she has already had some back-and-forth. It should
be noted that MinglePlus members are exempt.'

There is also another message limitation..if the emails exceed
a certain number and within a timeframe. This ones cures in minutes.
