Here are the formats of BrickLink URLs I find useful. Change the specific IDs to the IDs of what you want. Remember the -1 in most set numbers. Other suffix numbers are rare except for CMFs and advent calendars. I bookmarked these before making a text document list. Beware of URL automcomplete filling in a different ID number.
https://www.bricklink.com/catalogColors.asp lists color IDs along with other color information. I checked the ID-name list often enough that I saved it to my computer, sorted it by number, color name and type of color, and uploaded here -
http://www.mediafire.com/file/p1bbjv1zjbc6sjq/Color_List.xlsxNot Applicable is color ID 0, useful for checking things like stickers, and regular parts accidentally listed without a color
I mainly sell; because I have my own inventory I rarely buy on BL, so my links focus on sellers, but include many general and a few buyer links.
Store link has username rather than store name, like

Part and color - only new listings in the US. (You need to change only the first instance of the color code. It's easy to change N to U for condition, or remove the whole " %22cond%22:%22N%22, " for any condition

http://www.bricklink.com/catalogItemInv.asp?S=71310-1For a non-set item, like *M*inifig or *Gear* just use that letter and the item number.
Recent sets with a specific part in a specific color
If I can't find a part, it might be in a set I haven't finished sorting. This helps me figure out what sets to look through:

I use these most often for DUPLO but occasionally catch something missing or inaccurate for regular LEGO I handle

My Activity Overview
https://www.bricklink.com/myActivity.aspSeveral potentially useful bits of information, including status of your catalog contributions and forum posts. I keep track of items per lot, which includes subtracting the number of stockroom lots, and this page includes that number.
Contact about a particular order (there's a link near the bottom of the order detail page; I use this template much less often now that I noticed that. Just remove '?orderID=1234567' for the main page where use typesin username or order number)

You mean a buyer is scamming or a seller is?
Fortunately the worst I've had to deal with is nonpayment, which can be taken care of order by order and the BL system gets them if they make a habit of it.
