First, you may not know a very interesting fact about your Gmail email address : you can use your regular email address as firstname.lastname@example.org and also email@example.com.
Second, it is possible to append a plus sign (“+”) followed by any text to your Gmail user name and hence create as many email addresses as you want (e.g. firstname.lastname@example.org redirects to email@example.com). However, many websites do not allow the usage of the plus sign in your email address and this trick is easily recognized by email spammers.
A better solution is to remember that full stops (“.”) are not considered by Gmail (e.g. firstname.lastname@example.org redirects to email@example.com as well as firstname.lastname@example.org), so you can use them to properly filter incoming emails (e.g. use email@example.com when registering to websites and then filter those messages).

If you need to share the .tex source files of your work but they include comments that you would rather not distribute, you can use this simple in-line Perl script to removes comments automatically.
perl -pe 's/(^|[^\])%.*/$1%/' < old.tex > new.tex
When you’re asked for your .tex paper you probably also need to include all the files which are called there (i.e. images and bibliography) in order to make possible for the receiver to recreate the final .dvi (or .pdf) file correctly.
Here you can find a Perl script which collects all the files you call in your .tex file, and packages them up, together with the original .tex file, as a .tar file.
This works only if you’re using LaTeX, the ones using PDFLaTex should take a look here.
