I know one of the constant concerns is people wanting a WYSIWYG editor.
That includes me, by the way. I've even suggested one in the past... and now I want to share a new discovery... FCKeditor.
I don't even own Front page. For "traditional" website I've used NetObjects, which creates too heavy code for email. So I've been getting along with htmlarea, installed on my website using the sample configuration as a utility, having to open it in IE to format my email.
I've tested a number of routines that could be made part of ListMail Pro.
The bad ones?
I found Htmlarea clumsy, no longer supported or being developed, and wouldn't work with Firefox.
TinyMCE (which is used in WordPress blogs) is difficult; it seems to fight with me as a user, reformatting things.
Interspire has DevEdit. They put a trimmed down version in their SendStudio package that competes with ListMail. It's AWFUL. Changes all the html around, adding all kinds of things. Very difficult to use. Plus you have to pay for it.
So I vote NIX to all of those.
FCKEditor is easy to use... open source... and you configure it with templates if you so desire. You can try it with a 3 minute test here as I set it up for email formatting for my clients:
http://emailformatter.com/editor/index.php?user=cd&pw=5yearsUserID is cd password is 5years ... the link above should instantly get you past the login.
In the above example I turned off uploading files, browsing the server, etc. That is easily undone with a simple true/false setting in the config file, all options that would be desirable in a ListMail inclusion.
