SimonBradley (Premium Member) asked that question last month at an earlier stage in his quest than you and I gave the following answer uprated for the recently moved goalposts to accommodate Simon):

There are three ways of becoming a PM:

1 You can post 55 useful and informative items and ask sensible questions
having diligently searched the forum before bothering (busy Premium Members!)

2 You can know Jack Sh*t and post 55 dumb questions especially not having
diligently searched the forum first

3 You can know Jack Sh*t and post 55 dumb answers

or a combination of 2 & 3.

We all look forward to your contribution.
