To Start
1. To change your "Logo" you have to create a new Image as it is not text
...you will find the image to replace..(2 of them)...in the Images
folder...(create and upload)
2. I am not sure why you get the script error for the lot123 search however
are you using the Tools icon to create it in the editor or are you doing a
copy and paste from somewhere else....the Tools Icon creator has and is
working on all other sites ok..
3. The emails are sent to each person to confirm their existence before
being given permission to login.
this also proves that their email address is correct and that you are in
their excepted folder.
An email is not sent to you on each registration however it can be created
so that you have the option for admin to receive also when they confirm
registration.
