Any way to bypass the 60 sec PM'ing restriction?

I've just posted a thread in the forum market section and got ~10 personal messages and around the same count of people asked to PM them in the thread. I basicly have to send them a copy-paste text for the first time. If I want to PM 20 people, that's 20 minutes! Then I have to reply each of them, another 20 minutes, and then again and again if I have a lot of PM's comming.

Is there any way to bypass the restriction? Like membership or something like that.

 

You can use the multi user sending feature.

In the recipients username field type up to five usernames separated by a semi colon.

 

Just copy their names into the receipt column. It will save you a lot of time but it only allows 5 at a time.
