CMS Made Simple Forums

Hi there.
Were should i write in the meta informations and Google Analys script in the admin system? to get it work perfect ?

Your meta info can be entered in "Site Admin -> Global Settings" or you can simply add it in your template, depends how you prefer it.

For GA you can use GlobalContentBlock (turn wysiwyg off!!) or add it directly in your template.
Don't forget {literal} {/literal} around javascript code.
