Templates 

Hello. First, thanks for your contributions; you're doing some nice work. There are a couple of things I've noticed with your templates that could be improved, however. When you created a new version of Template:Cosmology at Template:Physical cosmology, and then set the old template to redirect to it, you hid the history of the template. Where possible, please put the replacement template at the same location as the old one, or move the old one to the new name, then put the new code in place. (If you're worried about making a mistake on the new template and messing up the articles it's used on, then use a sandbox.) If you do that, then not only do you keep the history of the page, but you make it easier for those of us that are watching the template to see the latest changes to it (i.e. those during and after the replacement). I've requested a history merge on Template:Physical cosmology to fix this (which means an admin will come along and merge the histories of the templates at some point).

Also, please make sure that you don't add extra whitespace (new lines) into the template, as that also appears on the articles if it's not in a noinclude tag. See  for an example of what I mean; your version had two extra lines at the bottom of the article, which were appearing in the articles the template was used on, whereas the problem is now fixed.

Finally, please categorize the templates you make. There's a whole load of template categories under Category:Wikipedia templates; the two you're most likely to be interested in are Category:Physics templates and Category:Astronomical templates (and their subcategories). Categorizing the templates makes it a lot easier for other people to find (and then use) them.

Thanks.
