Sorry but design is not something that is offered as part of support, but there are the gaz_html_header and/or gaz_html_navbar and/or gaz_html_footer templates that you can edit for each style as you prefer. Use absolute http:// links, not relative links, do not use JavaScript, use inline CSS, not external CSS files, etcetera, so that you have a better chance that the receiver's email reader does not strip out parts of the HTML email.
As for the permissions, also check that via the ACP ->
GAZ
-> Newsletters -> click a newsletter -> check the 'Usergroups allowed to subscribe' section, and via the User CP of your forum, check that you are subscribed to the newsletter. If you haven't seen it yet, you might find additional help with
GAZ
in the wiki
here.
Because the code is "visible source" there are no refunds, except in very limited circumstances. Unfortunately what you describe does not fall into that category, but if you wish to sell your license to someone else, and then do a transfer request from the
http://www.thevbgeek.com/glic.php page, you can do that.
