JOEL - In this universe and at this time there is no other God than the one we worship now. As far as we are concerned there is only one godhead(God the Father, Jesus Christ, Holy Ghost). Our scriptures and revelations we receive through our prophets are from the God of this universe and pertain only to us in this universe at this time. However, according to LDS doctrine, those of us who follow God's plan of salvation and are succesful at reaching the Celestial Kingdom(after we die and are resurrected), will have the opportunity to become Gods also; but we will be Gods of other universes and at another time in the eternal future. None of this can happen though until Christ comes again and begins the resurrection. Our bodies must first reunite with our spirits before we can enter the Celestial kingdom or whatever kingdom God decides to send us to. These and many other things must happen before anyone else from this universe can become a god. No other God has been recognized because there is only one God that we are concerned with as far as our own salvation and eternal life is concerned. People of other universes and at other times have their own God who they worship.

LAURA - Why are temple practises/ordanances so secretive. Not allowed to be discussed with new members or prospective members of LDS church?

The reasons why the temple ordinances are kept out of the public's knowledge has to do with the sacred nature of the temple itself and the things that are learned within. The Temple is literally the House of the Lord; a place where God Himself can come and reside if He so chooses. Because of this only those who are righteous and worthy followers of Jesus Christ, who have lived His teachings and kept the commandments, may enter and participate in the ordinances. Those who are new to the church need time to learn all they can about the gospel and prepare themselves spiritually so that they will be able to understand what they learn in the temple and so they will be able to keep the promises they make with God, that are an important part of the ordinances. The church even has temple preparation classes that help new members learn what they need to know and do before they can participate in the Temple. Normally a member will not be considered ready for the temple until at least a year after baptism.
This restriction of temple admitance and discussion of the ordinances is consistent with ancient practice when, for example, only specifically qualified persons were admitted into the holiest precincts of the Tabernacle. For admitance into the temple LDS Members must meet with their Bishops and obtain "temple reccommends" by correctly answering a number of questions that determine their status with God and His gospel. The function of local Church leaders in issuing temple recommends to church members is not only to establish the individual's worthiness and preparation but also to assure the sanctity of the temple.

"If any man defile the temple of God, him shall God destroy; for the temple of God is holy,"(1 Corinthians 3:17)

Matthew's council sounds a little harsh but would also apply:
"Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.."(Mat. 7:6)
