Mozilla projects are great.
-you are getting big and the growing use of Firefox, Thunderbird and Seamonkey has to implement more carefull use and control off extensions and add-ons delivered by Mozilla web.
It's important that you not recommend add-ons having sole purpose to marked a product, for example Ja-Jha. It's nothing wrong with the product, but I feel it does not fit as recommended, because it's fronting telemarketing of a simple company. It differs from other add-ons because JaJah is in fact a pay for product.

Thunderbird and Mailclient in Seamonkey is a very good mailklient. MailCatalog structure has to get altered so it's more flexible and safe to take care of important mail. I might be old fashion but I prefer a catalog structure that is compilable with OS and not explicit to the mail client.

Mail client is one of the most important programs in business and at home. E-mail is soon more preferred than ordinary mail, fast and low cost.
I've could have written a long list of wishes for future mail client. Example, Address book is made so it can be copied simple from Mail client to Word possessing. Address book is collected addresses over time and is a important document, loosing address book can be troublesome. I hope that in time people will change to other OSs then its important that mail client important documents is easily copied and saved before porting
