Re: ReplaceValuePlugIn

Salut Eric,

nice to have you on board :)
We have setup some informal rules for contribution. You get write access
to the svn in two ways:
1) you get immediate access to the svn if you got a recommendation by
developer that is already well known by the project (or a member); or
2) we review the first two contributions. If both are ok you will grant
write access. As you passed the 1st code-review round already according
to Michael, I would like to ask you, to send to your second contribution
to the devel-list for a review (if you have finished that work already)

I hope you understand this policy and I suppose the 2nd sample you
presenet will be a piece of cake for you? Alteratively you may tell us
(or me and Michael personally) about your programming experience.

Anyway, as it seems to me you will qualify ;) i ask you to already send
me your sourceforge account name (on my personal email), so i can
prepare anything for svn-write access.

cheers, currently from Germany (Btw. I met some people from Intevation
on the Intergeo fair)

stefan

@ Michael: thank you for reviewing! If you want you can commit the code.
Otherwise I will do in the next days.
