Why I am limited to send messages in here?

You may be encountering filters.....a lot of the women don't want messages from guys seeking intimate encounters....

they can set it up to block many things
age , intimate encounters , close by , etc etc etc

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.

Thanks soulfie
i forgot about that one
