Before Purchase: Lethe is not a plugin or blog. Demo front-end page just demo about Subscribe Forms and integration views (flash, custom forms etc). Do not expect full blog or website.

Please try to contact me before negative votes if you have trouble with Lethe. Lethe already passed beta-tests, but there too many servers available and server differences, hosting settings / permissions is not mean script faulty.
