Re: 28 Aug 2003 Commit - Horde/IMP Versions?

Amith,

Thank you for that great information.  It has cleared several things up 
for me regarding the Horde project as a whole.  With your responses and 
those of others on the horde-devel list, I believe I have a better 
prospective of the project and how I can better take part.

Keep up the great work.

Respectfully,


Gary
