Good questions. no problem letme take care of them:
1) conversion tracking plugin: you can use it for ANY tracking code that requires to be inserted in the BODY tag. (Most do, with rare exceptions for “analytics experiments” which requires it in the head tag). To insert BOTH google and bing, no problem, just paste the two pieces of code one after the other as you suggested. this is what i do when i use both.
2) that would depend on your sitemap plugin that you’re using. usually there is an option to exclude certain pages. it’s not done through this theme because it doesn’t produce sitemaps. also, if you use Google Webmaster tools to build sitemaps, you can usually set this from there. i forget the exact structure. if you can give me some details on your install i should be able to be more specific. how do you produce sitemaps?
3) 58×68 the one in the demo. but you can make it as WIDE as you like as long as it fits in the form, but keep the height to 68.
