1.) The license is based on open source license which you may find in several CPAN modules.

The WebApp license does not even bear passing resemblance (in neither content, spirit or wording) to the GPL or Artistic License. Since these are the two licenses under which Perl and (I believe) the vast majority of CPAN modules are licensed, your statement is simply false. There is no such thing as "the open source license", there are a variety of licenses which are recognised by OSI and the FSF, but WebApps does not seem to conform to any of these.

3.) The ajax popup you refer to is a test we make in version 2.0, and by the way it should work fine now on all Safari...or pre Safari browsers too.

Yep, works with Konqueror now, good job there! However, my original comment remains, unrequested popups are evil and I personally will not recommend or use a web software that uses them so needlessly.YMMV

Re: 4.) I do not perceive this as a two sides to every coin thing. It's hard to tell who one is talking to, since there seem to be two of your development team posting anonymously here, but as far as I can tell you have both made slanderous and extremely impolite statements which were totally uncalled for. That the only logged-on person supporting WebApp seems to be a total troll does not exactly strengthen your case. All in all your "side" comes across as enthusiastic but immature, if I may say so. Again, YMMV, but the way this discussion has been conducted does not at all inspire confidence in the platform you support/develop in me.
