If you have created an account on the forum and you get that the account needs to be approved before you can write a post.
Then you account got flagged by the Anti-Spam filter.
You then need to go to
http://multicommander.com/contact and send a message that you want to be approved.
(Do not forgot to specify what forum name you use)
I will then approve your forum account and you will get access to it.
I ignore all automatically sent approval requests for new accounts since 99% of all accounts that get flagged with requiring approval is because they are spam-bots or user that are flagged in a global database as a user that are just posting ads/spam.
