Kind Sir, if you are an ex-F105 Thunderchief driver or mechanic, or whatever, you need not apologize for being new to this forum. But, if you are assuming that screen name from having built a Revell model F105, it might be appropriate. There are people on this forum who are somewhat preoccupied with the date one first posts regardless of the poster's background whether you might be Brit Hume, Alexander Haig, Henry Kissinger, or George W. himself. Don't worry about it, press on.
