Wordpress:
Hi i was looking for a way to allow me add a option that i am select options like archive for next month, next 2 month, next 3month example.

I think it's pretty much automatic in Wordpress, they will archive your files by month unless you specify it otherwise. Some themes allow you to edit archive settings.

here's how to change settings from Wordpress

It is even included into the blogger CMS, which is rather simpler. So there is no any need for external modules to plug in.

any guide on how do i change that?

?? any help?

There are many ways to list archives on your site. It depends on the theme you are using.

1. There is a widget in the Widgets area for archives if your theme supports them.

2. You can alternately hard code the display of archives using wp_get_archives().
(You can use the "type" parameter to set it to weekly, monthly, etc...Wordpress will do the rest.)

3. You can search the plugins.

If your theme does not have an archive.php or category.php file, then Wordpress will use the index.php template to display the archives.
