Memorising e is quite easy; Here is a guide for only the first 15 decimal places of e ...

e ≈ 2.718281828459045 (to 15 decimal places)

We all know e as approximately 2.7 (or 2.71). The next bit is simple ... 1828 twice. That's all it is. Two-point-seven ... one-eight-two-eight-one-eight-two-eight. Next are the angles of a perfect right-angled isosceles triange ... 45° 90° 45°, in that order precisely. Say that now.

There is actually a factual piece of text for memorising fifteen digits about a president of some country elected twice in 1828 (true story!). I posted it in an 'e' thread in the This Is Cool forum a while back. A year ago I also posted links to pi mnemonics for those who want to memorise pi, for .... whatever reason?

]]>The easier one is just to encase the link in [url]tags.

e.g. [ url ]www.google.com[ /url ] (without spaces) gives www.google.com.

Alternatively, you could put a description of the link by doing [ url={link} ]{description}[ /url ].

e.g. [ url=www.google.com ]Search engine[ /url ], without spaces, gives Search engine.
