Hi Dave.
Being an Anchor is a business opportunity .
Anchors are entities that people trust to hold their deposits and issue credits into the Stellar network for those deposits. All money transactions in the Stellar network (except lumens) occur in the form of credit issued by anchors, so anchors act as a bridge between existing currencies and the Stellar network. Most anchors are organizations like banks, savings institutions, farmers’ co-ops, central banks, and remittance companies.
An Anchor basically backs up an asset for trading .
example of anchors :
Ripplefox.com
CNY anchor in China. Allows you to send money to any bank or Alipay account in China.
NaoBTC.com can help BTC move faster and exchange with other digital assets easier.
you can find a good list of anchors here http://publicstellar.com/currency_list.php
TO become an Anchor .
You need to do the following:
WEBSITE
You need a website that user would visit to make a trade with you, you can do this in so many way. you could get a profession web designer. or set up a facebook messenger bot (https://www.facebook.com/Tonaira-114369132532315/) try the messenger and see an example ,
ISSUE ASSET/TOKEN 
You must already have a wallet public and secret key.
2 lumen wallet address is needed.
the issuer and the distribution/base
An issuing account used only for issuing and destroying assets.
A base/distribution account used to transact with other Stellar accounts. It holds a balance of assets issued by the issuing account.
To issue an asset. kindly have up to 50lumen in both issuer and base account .
you can issue via http://publicstellar.com/create/ (this will publish you straight away )
or use https://poliha.github.io/stellar-tokens/
Publish via (www.publicstellar.com)
not really necessary.
if you made use of the publicstellar asset creator you have been published on the website if not you should visit the website and http://publicstellar.com/register.php register.
Federation server and TOML file
One of the issue that have been simplified this month with very good example..
Federation: which allows a single Stellar account to represent multiple people.
This is used as placeholder for the long lumen address .
a wallet address : GAIUIQNMSXTTR4TGZETSQCGBTIF32G2L5P4AML4LFTMTHKM44UHIN6XQ
can be represented with Dave*levine.com
and if any user use the Dave*levine.com , it will resolve to that address above .
a very simple federation set up using php is https://github.com/slideloft/php-federation/tree/master
TOML file is what helps the lookup locate the federation server.. you can call it the DNS , it is located in the directory /.well-known/stellar.toml
an example is https://tonaira.com/.well-known/stellar.toml
FEDERATION_SERVER="https://tonaira.com/fed/"
