I would suggest to remove WinPT from your Linklist. it seems as the project might be dead and the offered Release Candidate can not cope with GnuPG 1.4 (and I did not find any version of WinPT who could - but the "normal" Version to download should be UP TO DATE!).
Therefor a Windows user who does not his way around too good might stick with the GnuPG version (iirc 1.2.2) coming with WinPT which is dangerous. Also updating afterwards to version 1.2.7 is not that easy as it is not available as a precompiled version for Windows.
So please think about removing WinPT - sadly as it is, I always normally use/used WinPT - and adding GPGshell. it just seems to be the more active project with more features ...
Release Candidate 1.0: April, 28th, 2003
