you are already at 'basic user' , so you should be able to send PMs already. (its only new users that can't PM)
generally, Im not going to start raising user levels... the idea is that brand new users cannot PM, they have to interact with the community publicly first, this raises their 'trust' - it helps against things like spam.
also, as per my edit on the first post... I would recommend against lots of users spamming johannes, he will make stock available as soon as he can, nothing is going to change that ... and the more time he spends on support here, the less time he has for other things ... building/developing/shipping. thats my personal opinion at least.
