A quick note to say Hi and thanks for the great pool, Pooler!

Thank you!
So, Pooler, if you have time, please explain your current stance on Merged mining and if the coins are going to the bonus LTC.
Yes, that's how it works. It is briefly explained on the pool's homepage, as well as in the FAQ and in the first post of this thread:
Since September 11, 2014, the pool supports merged mining of Dogecoin and other cryptocurrencies, resulting in higher payouts than with a regular Litecoin pool.
Every valid share you submit to this pool is instantly credited to your account at the current pay-per-share (PPS) rate. This rate, expressed in litecoins, also takes into account merged-mined coins such as Dogecoin, resulting in higher payouts than a regular Litecoin pool. Thanks to merged mining, you have to pay no fee; in fact, your earnings may even be higher than with a 0-fee PPS system.
[...] Thanks to merged mining, a technique that allows multiple cryptocurrencies to be mined simultaneously, it is possible to achieve PPS ratios higher than 100%. [...]
