Hello Steemit,

this is the second part of the series "how @wang is doing it"
You can read the first post here https://steemit.com/hacking/@seagul/steemit-vote-bot-like-wang-for-introduceyourself

Like i said in my first post, i will publish the post bot for the introduceyourself section

## Full python code for post on every new post @introduceyourself
    import time

    from steemapi.steemnoderpc import SteemNodeRPC
    from steembase import transactions

    currentTime = int(time.time())

    message = "Welcome to Steemit!"

    user = "yourUserName"
    wif = "yourWifKey"
    category = "introduceyourself"

    rpc = SteemNodeRPC("wss://steemit.com/wstmp3")
    for post in rpc.stream("comment", start=currentTime):
        if post["parent_author"] == '' and post["parent_permlink"] == category:
            try:
                expiration = transactions.formatTimeFromNow(60)
                op = transactions.Comment(
                        **{"parent_author": post["author"],
                           "parent_permlink": post["permlink"],
                           "author": user,
                           "permlink": post["permlink"],
                           "title": "",
                           "body": message,
                           "json_metadata": ""}
                )
                ops = [transactions.Operation(op)]
                ref_block_num, ref_block_prefix = transactions.getBlockParams(rpc)
                tx = transactions.Signed_Transaction(
                        ref_block_num=ref_block_num,
                        ref_block_prefix=ref_block_prefix,
                        expiration=expiration,
                        operations=ops)

                tx = tx.sign([wif])
                tx = transactions.JsonObj(tx)

                rpc.broadcast_transaction(tx, api="network_broadcast")
                print("Posted!")
                print(post["title"])
            except Exception:
                print("Oops! Posting")


This script will write "Welcome to Steemit!" under each new post in the introduceyourself section. 
@wang was a little bit more creative and has done a [multiline string] message. Example: http://stackoverflow.com/a/10660443
