Just started working on a community forum that has already been set up and implemented with InstantForum it's my first time using this type of forum I have all the access to the admin section etc and have been playing around with things, finding my way around. The person who set it all up is no longer around so I need some help working a few things out.

1. There is a forum header set up with a title and some introductory text where would I edit this introductory text?

2. The date and format is in american format i.e dd/mm/yyyy I have changed it in managesettings/general settings to the date format I want but still it stays as the format dd/mm/yyyy? any ideas what I might be doing wrong there?

3. Also was hoping to change some things in the Personal Details options where people can write there interests and biography i want to rename these sections to favourite bands / favourite movies is this possible and where would I change the fields?

Any help appreciated, cheers

I'm sorry about the delay, answering your questions:

1. There is a forum header set up with a title and some introductory text where would I edit this introductory text?

- I'm not sure if I undertood it, but you can change any text in the forum, the Title you can change in the Admin area - General Settings. 
Others modifications you can find some help in the link below:

2. The date and format is in american format i.e dd/mm/yyyy I have changed it in managesettings/general settings to the date format I want but still it stays as the format dd/mm/yyyy? any ideas what I might be doing wrong there?

Could you please try to insert the line below in your web.config file in the system.web area?

<globalization requestEncoding="windows-1252" responseEncoding="windows-1252" fileEncoding="windows-1252" culture="it-IT" uiCulture="it-IT" />

You can see the culture configuration table at the link http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemGlobalizationCultureInfoClassTopic.asp

So if your languague is not Italian, you can change it for the correct one, as indicated in the table.  Also I've attached here my web.config file for you to know where you can insert this tag.

3. Also was hoping to change some things in the Personal Details options where people can write there interests and biography i want to rename these sections to favourite bands / favourite movies is this possible and where would I change the fields?

You can change these texts in the Globalization\en-US\resources.xml file
