I noticed that adding %%page%% to the title for my "tags" adds this:
TagName - My Site Page of 1
On the first page of the tag. Also, there is no pagination for that tag, as there are only 3 posts available. It seems a little weird that it would already be saying Page of 1, instead of just having "TagName - My Site" for the first page of the tag.
This is the setting I'm using:
%%tag%% - My Site %%page%%
Am I doing something wrong or is it a bug?
