Without seeing your code, I can only give you generic answers.
QUOTE
1) Only show the single most recent entry. (I dont mean the list of archived messages!)
In your main index:
CODE
Change
<$MTEntries$>
to
<$MTEntries lastn="1"$>
QUOTE
2) Exclude entries from a certain category so that they are only displayed in the Archives list and not shown as the latest message.
Again, in your main index:
CODE
Change
<$MTEntries$>
to
<$MTEntries category="category1 OR category2 OR category3"$>
In place of nameofcategory1 you'd enter your category name, such as Current or whatever. This will then show entries only from your listed categories. I don't think you can currently set category= for an excluded category, but instead you must list all the categories you want included.
There are some plugins for excluding categories, but MTFilterCategories doesn't work with MTEntries, and MTExcludeCategories doesn't work if you use lastn= attribute.
Someone else may know a more elegant way to exclude categories (and I'd like to know what this as well!).
Cheers,
