So first beta of sfEmailTemplatePlugin is finally released. Thanks a lot for all the guys who commented an initial post about this plugin (Eric, Gerald, COil and James). I must say this is really helpfull to read these warm words and it inspires me to work better.
This first beta does not include tag support for email template so far but it covers all the other declared functionality. Read Wiki page for futher details sfEmailTemplatePlugin.
Unfortunately, I wont be able to work on tags functionality in the nearest time so if someone will have a chance – everything is in his hands. There is already defined sf_tag_template table where email template tags must be stored.
