Great! Thanks. I misread the help page that you pointed me. I didn't catch on to the subtle distinction between "excel range screenshot" and "excel copy&paste range". My suspicions were heightened by a recent posting where a user included a screenshot of 10x30 range of numbers, and he is asking for help in determining the "running" IRR.
If a moderator reads this, I have a suggestion.... At login, provide a banner that suggests that people use the "copy&paste range" feature of XL2BB to include relevant parts of Excel files, and specifically __deprecate__ the use of uploading screenshots except for the simplest examples (a few cells of data). Similar to the login banner at excelforum.com, although they are suggesting that users attach an example Excel file because they allow it.
