Hello gm9,
Not surewhere else to post this...
Just letting you know that when you added the new spam tab in the mail window, you removed the <include>_ProfitUI_Mail_Signatures.txt</include>
As a result, the add signatures button doesn't work.
Sticking it back in should fix the siginatures
<Text DynamicData="/GameData.Self.Name" Name="Selfname"></Text>
<include>_ProfitUI_Mail_Signatures.txt</include>
<Button Name="RetrieveSignature"></Button>
Hope this helps,
Narzoo
